Workaround 'function is never used' cppcheck style warnings

* tests/test.c [DBG_HDRS_ALL || MAKE_BACK_GRAPH] (GC_DEBUG): Do not
define if CPPCHECK.
* tests/test.c (NO_TEST_HANDLE_FORK): Define also if not GC_PTHREADS;
do not define if CPPCHECK.
* tests/test.c: Include gc_inline.h, javaxfc.h if CPPCHECK.
* tests/test.c [!PCR && !GC_WIN32_THREADS && !GC_PTHREADS] (main): Call
GC_noop1(&WinMain) if CPPCHECK and not NO_WINMAIN_ENTRY; call
GC_noop1(&Init) if CPPCHECK and RTEMS.
* tests/test.c [!PCR && !GC_WIN32_THREADS && !GC_PTHREADS && CPPCHECK]
(UNTESTED): New macro.
